Actually, I do both, but let's get back to your post as there is educational value for others in what you don't understand.

Quote from TraderZones:

As with most TASC, Futures, or other mag articles. Long on claims, opinions, cherry-picked examples/backtests, etc. Short on evidence...

It is an article backed by (2) books and thousands of pages at my web sites. I have posted performance data from professional trend followers for over a decade. That is not evidence of the power of systematic trend following?

Quote from TraderZones:

You of course, are going to supply overwhelming, statistical PROOF that systematic traders are best?

In addition, their rules of buying and selling may be written, but you hedge your claim "assuming based on". But that is not what you were trying to prove. This holds for EVERY type of trader "Day traders, scalpers, investors, etc." Are best, assuming yadayada

And where is it proved systematic traders follow their system religiously? ET is full of people complaining they have a clear system, but make errors, manage money poorly, cannot make money, blow out, etc.

The trend followers I write about are all secretly making discretionary decisions for all those decades in their highly regulated funds? Further, that's why they all have such correlated performance, right? Let's assume you are right in your vision, what then are they doing when you examine performance such as at www.iasg.com?

They think they are profitable, but instead are Hold&Hope or Averaging down. And many of them ARE "systematic" But they constantly subvert their plan when exposed to large positions.

Who and what are you talking about? I think you would learn a great deal from my (2) books and this TraderZones.
